This application is a division of my former application, Serial No. 569,467, iled June 19,

-'carbon oils or asphalts by combiningsame with water and a suitable emulsifying agent.

Among the salient objects of the invention are to provide a processwhereby emulsions may be formed continuously of two or more materials either under substantial pressure or at atmospheric pressure to provide a process which under pressure, increases the boiling point of heavy viscous materials and raises the temperatures used without evaperation; to' provide a process which is so constructed that'it is economical and at the same `time is capable of a maximum eiiiciency; to provide a process in which -emulsions can be made continuously, and in which the` materials used in making the emulsion are continuously circulated and mixed, at the same time being subjected to heat and pressure.

pressure inside thesystem. Outlet 11 is provided with a valve 15 and inlets 9 and 10 are provided with valves 16 and 17. The conduit may be provided with externa-l heating apparatus or burners 18 for the purpose of heating the material inside the conduit. The entire apparatus may be mounted on the standards or uprights 19.

One method of operation of the apparatus y may be as follows: The conduit 1, through the cover 8, is charged with a heavy viscous mixture of colloidal clay, as an emulsifying agent, and water. The shafts 2 and 3 are set in motion so that the propellers 4 and 5 are working in a direction to produce a'circulation of said'material around 'the conduit 1. The material to be ni-xed may be brought t0 the desired temperature by the application of heat as shown in the drawin' When the clay and water mixture is of t e proper consistency, inlet valve 16 on inlet 9, which in this instance,` is used for the inlet of asphalt,

is opened, and this asphalt, having been preen the valve 15 `on the outlet 11 is opened to allow the same amount of material to pass out as is being fed to the apparatusthrough the inlet 9. When the proper. percentage of asphalt is mixed with the original charge of the lconduit 1, which may be anywhere from v99% down, the inlet valve 17' is opened to allow a continuous iow of the 'emulsifyin agent, which'is, in this instance, colloida clay mixed with water, and the outlet valve 15 opened that much more.

As the lmaterials enter through the inlet valves, they are immediately taken up by thecirculationthrough the conduit 'and formed into a permanent emulsion and the finished p emulsion is drawn from the outlet 11.

As a feature'of my invention, `it will be l noted that the (process may be operated under any pressure esred, thereby permitting the use of high melting point asphalts having a` i *boiling point of 250 to 4009 F.,'or more',"m H f 14, which is preferably aloaded or automatic that the prop'eramount of pressure being i 50 valve, which latter is used to regulate the v exerted naturally increases the boiling point 10 Asaid materials.

I claim as my invention: Y

1. A process of making emulsions, which comprises subjecting a base material, water and an emulsifying agent to agitation to disperse the base material in the water, im-

parting a cyclic circulation in a horizontal direction to said dispersion, maintaining. said cyclic circulation of said dispersion while introducing fresh quantities of base material, water and emulsifying agent to the circulatdrawing predetermined amounts of' dispersion from said circulating mass substantially at a rate and in a quantity corresponding to the rate and quantity of fresh materials being fed to the circulating mass.

2. A process of making emulsions, which comprises subjecting a base material, water and an emulsifying agent to agitation to disperse the base material in the water, imparting a cyclic circulation in a horizontal direction to `said dispersion, maintaining said cyclic circulation of said dispersion while introducing in separated streams, fresh quantities of base material, water and emulsifying agent to the circulating mass to be dispersed, and withdrawing predetermined amounts of dispersion from said circulating mass.
